SPECIFICATION forming part of Letters latent No. 388,977, datedSeptember 1888.

Application filed May 14, 1888. Serial No. 273,571. (No model.)

To all 2072 0721, it may concern.-

Be it known that I, ISAAC HULME, of Yaquina, in the county of Benton andState of Oregon, have invented a new and Improved Rail-Punch, of whichthe following is a full, clear, and exact description.

The object of the invention is to provide a new and improved punchspecially adapted for punching apertures in rails for the passage ofbolts to secure several rails together, and for other purposes.

Theinvention consists in certain parts and details and combinations ofthe same, as will be fully described hereinafter,and then pointed out inthe claims.

Reference is to be had to the accompanying drawings, forming a part ofthis specification, in which similar letters of reference indicatecorresponding parts in all the figures.

Figure 1 is a side elevation, partly in sec tion, of the improvement asapplied to a rail shown in section. Fig. 2 is an end elevation of theimprovement, and Fig. 3 is a sectional plan view of the punch.

The improved punch A is provided with an Lshaped frame, B, having at itsupper arm a handle, 0, for conveniently moving the device from place toplace. On the end of the other arm of the frame B are pivoted the endsof a U-shaped bar, D, extending along the base of the rail E. On theouter end of the upper arm, B, is pivoted the vertical arm F, having alongitudinal aperture, F, and provided with a foot, F, passing throughthe opening of the U'shaped bar D and having an offset, F adapted toengage the bottom of the middle part of the U-shaped bar D, as shown inFig. I. On the inner end of the arm F isheld the die G, made in the formof a collar and opening into the aperture F. In the frame B screws thepunchscrew H, provided on its outer end with a square or hexagon head,H, for applying a wrench or other instrumentto turn the screw II. On theinner end of the latter is formed a recess, H", in which fits the shankI of the punch I, provided with a collar, I resting against the innerend of the screw H, as illustrated in Figs. 1 and 3. On the outer end ofthe punch I, and in its center, is formed the point 1", adapted to fitinto the centeringmark punched on the body of the rail 1*]. A pin,

J seen red in the screw H, passes through an annular groove, 1, formedon the shank I of the punch I, so as to secure the latter to the screwH. The central line of the screw H and punch I coincides with the die Gwhen the several parts are properly adjusted, as shown in Fig. 1.

The operation is as follows: In order to place the punch A on the rail,the screw II is moved to its outermost position. The barD is passedunder the base of the rail E, so that the top arm of the frame 13 restson the head of the rail E and across the same, as shown in Fig. 1. Thearm F then hangs vertically and passeswith its foot F through theopening of the U-shaped bar D, and has its project-ion F engaging thebottom of the middle part of the U-shaped bar D. The outer end of thedie G then rests against one face of the body part of the rail E. Theentire punch A is then moved longitudiually on the rail E until thepoint I of the punch I is over the punched mark on the body of the railE. The operator now turns the screw H by suitable means, so that thescrew H moves inward and brings the outer end of the punch I against theface of the body of the rail E, opposite the die G. A further turning ofthe screw H causes the punch I to force an aperture in the body of therail E, the punched part of the latter passing into the opening of thedie G, which corresponds with the punch I. The punched partof the rail Ecan pass out through the opening F in the arm F.

It will be seen that the apparatus is very simple and durable inconstruction, effective in operation, and is specially intended tosupersede the ratchet and drill now generally in use for the samepurpose.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is-

, 1. In a rail-punch, the combination, with a frame, of a screw screwingin the said frame, a punch carried by the said screw, an arm pivoted onthe said frame, a die carried by said arm, and a bar connecting the freeend of said arm with the frame below the screw, substan tially as shownand described.

2. In a raihpunch, the combination, with a frame, of a screw screwing inthe said frame, a punch carried by the said screw, an arm pivotallyconnected with the said frame, a die held in the said arm,anda barpivotally connected to register with the punch, and a foot, F, on [owith the said frame and serving to lock the its free end provided withaprojection, F and said arm in place, substantially as shown and theU-shaped bar D, pivoted to the framebelow described. the screw andreceiving the free end of the 3. The combination, with the angular frameI arm F, substantially as set forth.
